Currently when you use Issue Navigator to export to CSV, as part of the export, one of the fields provide is "Epic Link Summary"

However when you use the Jira Cloud functionality to "Open in Microsoft Excel", this field is not available for extract - only the "Epic Link" - the ID

It would be EXTREMELY useful to include "Epic Link Summary" as available field when using  the Jira Cloud functionality to "Open in Microsoft Excel" - since it provides pertinent details about the ticket & also the Epic that it is a child of.
